stress-tests: improve stress tests

Browse Source 
Implement the following improvements in the stress-tests container:

- Show a warning message if an archive file is not found for USB
read/write stress tests
- Show a warning message if Internet is not available to generate
network loads
- Uses 4 different iperf public servers, in case one fails to
connect.
